huge, to admonish
誧 centers on using words to correct or guide: admonishing someone, or speaking with great authority or forcefulness. The "huge" sense likely extends from the idea of weighty, powerful speech.
誧 combines 言 (speech) with 甫, which likely contributes the sound and may carry a sense of spreading or extending, suggesting speech that reaches out to correct or impress.
Words 言 beside 甫, which looks like a hand holding a tool, can remind you of someone using speech to point out faults—admonishing with a huge, authoritative voice.
For ホ, imagine a huge, admonishing voice shouting "Ho!" to get attention: Ho -> ホ, and the words 言 carry the correction.
